- User accounts
- Student progress and projects
- The "levelbuilder" content creation tools
The server for the Code.org website, a Sinatra application responsible for:
The JavaScript 'engine' for all of our tutorials, puzzle types and online tools. It gets built into a static package that we serve through dashboard. Though there are currently some exceptions, the goal is that all JS code ultimately lives here, so that it gets the benefit of linting/JSX/ES6/etc. Start here if you are looking for:
- The Hour of Code tutorials: Star Wars, Minecraft, Frozen and Classic Maze
- Tools like Artist, Play Lab and App Lab
- Other core puzzle types: Maze, Farmer, Bee, Bounce, Calc, Eval
- Other JS code consumed by dashboard and pegasus.
- aws: Configuration and scripts that manage our deployments.
- bin: Developer utilities.
- cookbooks: Configuration management through Chef.
- shared: Source and assets used by many parts of our application.
- tools: Git commit hooks.
